SPECIFICATION forming part of LettersPatent No. 613,522, dated November 1, 1898.

Application filed Tune 29,1898. Serial No. 684,753. (No model.)

T0 all whom it may concern:

Be it known that I, DE WITT LOOMIS, of Detroit, in the county of Wayne and State of Michigan, have invented certain new and use ful Improvements in Draft- Rigging; and I hereby declare that the following is a full, clear, and exact description thereof, reference which form part of this specication.

This invention is an improvement in draftrgging for railway-cars; and the object of my invention is to provide a double or tandem draft-rigging of simple construction and having few parts, so that any broken part can be easily replaced and which can be easily and cheaply substituted for the forms of draft-riggingnow in use by most railroads, as many of the parts of my rigging are like those usually found in the draft-rigging now in common use.

The invention therefore consists in the novel construction and combination of parts hereinafter described and claimed, and illustrated in the accompanying drawings, which form part of this specification, and similar letters of reference thereon represent similar parts throughout the gures.

Figure l is a side view, partly sectional, of a draft rigging embodying my invention. Fig. 2 is a cross-section on line 2 2, Fig. 1. Fig. 3 is a plan view of Fig. l, and Fig. 4 is a sectional view of a modification thereof.

A A, Fig. l, are the draw-bar timbers, to which are attached the side plates or followerguides B B, made of iron and firmly secured to the timbers A by bolts b. The guide-plates B are set into recesses in the timbers A, as shown, but are provided with anges B at each end, which serve to prevent the timbers A A from breaking out at the points where the guide-plates are let in them. The guideplates are also provided with vertical stops C c C C2 c2 C3 c2, as shown, and to the lower by bolts b3, upon which bar the followers D D D2 D3, hereinafter described, rest.

The follower D is placed between stops C c and limited in its movements thereby. Follower D' is placed between stops C C2, folbetween stops C3 c3.

A yoke or strap E is solidly and firmly fixed to the end of the draw-bar F by the bolts f or in other convenient manner, and said yoke can be made of one piece, as shown in the drawings, or in other desired manner, its exact construction not being essential. This yoke extends between the guide-plates B B and surrounds all the followers D D D2 D3, resting upon barsV B3, said followers being held in their normal position respectively against the stops C C C2 C3 by the pressure of coil-springs H h and H h', interposed be tween the followers, as shown.

Supported in central guide-openings in the followers D D is a short rod g, which transxes and suspends the springs H h, as shown, and supported in openings in the followers D2 D8 is a similar rod g', which transfixes and suspends the springs H' h. Interposed between the lfollowers D D2 and between the ends of the rods g g' is a plate g2, loosely hung upon and guided by the yoke E, as shown. The springs H h and H h' may be of any desired construction, and, as shown, springs h h' are smaller than and arranged inside .of springs H H', respectively. It will be noted that the rods g g are not directly attached in any way to either the draw-bar F or the yoke, but are supported by the followers and rest loosely in the guide-holes therein.

In coupling cars or buffmg the end of the draw-bar F will first strike against the follower D, thereby compressing the outermost springs H hagainst the follower D', which is held by stops C. At the same time it can push the rod g against plate g2, which contacts with follower D2 and causes it to compress springs H h against follower D3, which is held by the stop C3. In the pulling strain the action wouldbe reversed. The inner end of the yoke E would strike against follower D2 and compress the springs H h' against the follower D2, held by stop C2. At the same time the rod g is pushed forward against plate g2, which presses against follower D and compresses springs H h against the follower D, which is held in position by -the stop C.

By shortening the rod g the springs H h could be compressed upon the bufiing strain before the springs H' h' were compressed,

ICG

and by shortening rods g springs I-I h could be compressed on the pulling strain before springs H 7L.

It will be seen that by this construction the parts can be very readily arranged so as to successively or simultaneously compress the sets of springs, as may be desired.

In Fig. 4.- I have omitted the plate g2 and the rod g', and the followers D D2 D3 may be left imperforate, the pin g still passing through the follower D. In this construction onwthe draft strain springs H II will be compressed, but on the buffmg strain both sets of springs will be compressed, as rod g will strike the follower D2 and cause it to compress the springs H' h along with the springs II h. It is obvious that the same effect would be realized if the rod g passed through the follower D and struck again the end of the draw-bar.

I-Iaving thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

l. In a draft-rigging, the combination of the draw-bar, the guide-plates, the four followers supported thereon limited in their movements by stops on said guide-plates and the springs interposed between the iirst and second, and third and fourth followers, and a rod or pin passing through a set of springs and through an inner follower, and the yoke attached to the draw-bar and surrounding the followers,springs and rod, for the purpose and substantially as described.

2. In a draft-rigging for cars, the combination of the opposite guide-plates, the followers mounted thereon, springs interposed between the first and second and third and fourth followers, the movable piece interposed between the second and third followers, and a rod supported by said followers contacting said piece; with the draw-bar and yoke attached thereto, surrounding the followers, springs and rods, for the purpose and substantially as described.

3. In a draft-rigging for cars, the combination of the opposite guide-plates, the four followers mounted thereon, and limited in their movements by stops on said guideplates; springs interposed between the first and second, and third and fourth followers, the pair of rods supported by said followers respectively transfixing the springs; with the draw-bar and yoke attached thereto, surrounding the followers and springs for the purpose and substantially as described.

4. In a draft-rigging for cars, the combination of the opposite guide-plates, the four fol lowers mounted thereon, and limited in their movements by stops on said guide-plates; springs interposed between the first and second, and third and fourth followers, the pair of rods supported by said followers respectively transfixing the springs and the movable piece interposed between the inner ends of said rods; with the draw-bar and yoke attached thereto, surrounding the followersi springs and rods, for the purpose and substantially as described.

In testimony that I claim the foregoing as my own I aiiix my signature in presence of two witnesses.
